MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 508,202, dated November7, 1893.

Application filed January 31, 1893. Serial No. 4601323- (NO IDOGL)water, bringing said currents in contact withv the milk and inconnection with it and the surrounding water cooling the milk.

With these general objects in View the invention consists in certainfeatures of construction hereinafter specitied and particu larly pointedout in the claim.

Referring to the drawings:-Figure l is a perspective View of anapparatus constructedv in accordance with my invention the same beingshown open. Fig. 2 is a vertical longitudinal sectional View of theapparatus. Fig. 3 is a transverse sectional view.

Like numerals of reference indicate like parts in all the gures of thedrawings.

In constructing the apparatus yI employ a box or casing, and the samecomprises a front and a rear wall designated as 1 and 2 respectively, abottom 3, opposite open ends, and a removable cover 4t. Within the openends of the casing there are secured screen frames 5, the same beingcovered by a reticulated cloth 6 adapted to permit .of a freecirculation therethrough of air and yet exclude anyfforeign bodies, asdust, dac. Seated removably is a metallic tank 7and in the operation ofmy invention the aforesaid tank is nearly if not quite filled withwater. Into this tank there is placed af series of creaming pans 8, theupper edges of the pans being slightly above the water line. v

This completes the construction of my invention and the operation of thesame, though obvious, I will briefly explain as follows: Having lled thetank with water and placed 5o the creaming pans in position the lid 4 isclosed', whereby, as will be seen, dust, dac., is excluded from theinterior of the apparatus, as are also insects-stoom &c. The ends of thecasing being left open it will be seen that a current of air is inducedto enter one end and pass through the apparatus over the body ofwaterand out the other end. The contact of the current of air with thebody of water lowers the temperature of Lthe air, the water beingevaporated by such contact; the

cool air passing over the milk in connection withthe body of watersurrounding the pans serves to promote and accelerate the raising ofcream thereon. "it will thus be seen that without the use of ice orother artificial refrigerating means 1 am enabled to promote 0raccelerate raising creamupon the surface of milk, and I have found thesame to be much more expedient than the ordinary manner of setting thecreaming-pans in milkhouses and similar structures, in that, as is wellknown to those conversant with cream raising, the setting of milk in theouter atmosphere greatly facilitates the raising of cream and also tendsto preserve the milk and maintain the 'same sweet for a much longer timethan where the milk is inclosed in tight coolers, milk-houses, and thelike, in that the animal odors can freely pass therefrom, and a constantventilation is maintained. I

Having Y described my invention, what I claim is- In a milk-cooler ofthe class described, the combination with a rectangular casing havingopposite open ends, and screens arranged therein, of an oblongwater-receiving open or coverless tank arranged between the ends Withinthe casing and of a less depth than the screen-frames,-and a series ofcoverless creaming cans arranged. in said tank, and agreeing in depththerewith, substantially as specilied.

- In testimony that I claim the foregoing as my own I have heretoaffixed my signature in the presence of two witnesses.
